UNETE@ STATES AEON JOHNSGN, OF BROOKLYN, NEVI YORK,

APPARATUS FORl PACKENG COMMINUTED MATERIAL.

Application sied July 1,

To all whom it may concern.'

Be it known. that I, ARON JOHNSON, a citi- Zen of the United States, anda resident of the borough of Brooklyn, in the county of Kings, city andState of New York, have invented certain new and useful improve`l mentsin Apparatus for Packing Comminuted Material, of which the following isa specification.

This invention relates to apparatus for packing ground or comminutedmaterial, suoli as cork mixed with a suitable binder `into stickscommonly termed cork sticks to constitute a lining materia-l for closurecaps of the crown type for receptacles.

In producing this lining material, the crown or comminuted' cork withthe binder is packed under vtamping pressure in tubes into cylindricalform, and after being packed into the tubes is baked to retain the corkin a compact and rigid though yielding mass from which mass portions ofpredetermined thicknesses are sliced.

lt is the primary object of the invention to provide apparatus to packground or comminuted cork with a binder into cylindrical form in anovel, more efficient and quicker manner.

in the production of this' class of material it is essential that thepacked material be substantially of the said consistency throughout, andto attain this result, so far A as is known, it has heretofore been thepractice to provide a support for a tube or a series yof tubes and feedsuccessive increments of materialinto one end of the tube underpressure, the tube or tubes being successively moved to a series ofplungers and the successive. plunge-rs being arranged to have apredetermined ymovement and a tamping pressure applied thereto; and itisa further object of the invent-ion to provide an apparatus in whichsuccessive increments `of material are fed into opposite ends of thetube or a series of tubes.

lt is another object of the invention to provide a carrier for a tube ora series of tubes to position the same with relation to material feedingmeans, and as the tube or tubes are filled to discharge the same and"position another tube or series of tubes relative to the feedingvmeans.

ln carrying out the invention provide a 'plurality of hoppers or ahopper vhaving a pluralit'yxofoutlets and arrange pockets at 1920.Serial No. 393,405;

the hopper outlets, said pockets being arranged in spaced alignment andadapted to receive predetermined quantities ofmaterial, with means toshut off and open said pockets to the hopper' outlets and regulate theamount of material. delivered into the same.` Means are provided tosupport a tube or a series of tubes in horizontal position with theopposite ends lthereof in register with the pockets, plungers beingoperable to deliver the material from the pockets into opposite ends ofthe tubes `as successive increments of material by having a series ofmovements imparted thereto of successively decreasing extent. Means areprovided to intermittently rotate the tube ,support to deliver thefilled tubes from the support and position successive tubes to thefeeding means, said means also operating to maintain the support againstmovement during the periods of rest. l

Similar'characters of reference' designate like parts throughout theVdifferent views of the drawings. y

Infthe embodiment of my invention illustrated in the drawings, a pair ofmembers 16 (Figure 10) are mounted on the projecting ends of'rods 23engaging in openings 24 of said members, said rods being mounted instandards 18 and 25 mounted upon a base These members 16- are arrangedin spaced relation below hopper outlets 20 which may consist ofv outletsfrom'a single f hopper or a plurality of hoppers, resting upon' saidmembers 1'6 and fastened thereto by screws or bolts passing throughperforations in the flanges 21 (Figure 7) of the hopper outlets andthreaded into the memk bers 16.y The members 16 have a series of pockets22 in the form of recesses extending transversely of and out through thetop of said members with the bottom wall of circularv form. Thesepockets are arranged to extend in an arc of a circle Whose axis lies inthe axis of a shaft 17, journaled in` a. down- Wardly extending arm ofsaid members 16, and saidpockets are adapted to receive materialfromkthe hopper outlets, as clearly shown in Figure 4.

As stated, it is an object of the invention to feed successiveincrements of material into opposite ends of a tube or tubes, and forthis purpose a support is provided to support a tube or tubes 26 inhorizontal position with the opposite ends thereof in register with theopposed material receiving pockets 22, and from which pockets thematerial is fed into the'oppos'ite ends of the tubes; rlhis support isin the form of a turretV comprising a pair of heads 27 fixed upon theshaftl? in spaced relation, said heads having equidistantly spaced:recesses 23- (Figure 12) extendingaround the circumference of the headsto constitute seats for the engagement lof the ends ofthe tubes andhaving flanges 29 with perforations 30 to register With the recesses inthe heads and openings in the tubes seated in such recesses. This turretis adapted to be intermittently rotated to successively present a seriesof six tubes, to be simultaneously filled, one tube being in registerwith each of the pockets 22 of the members 16. While the presentapparatus is designed to present a series of six tubes to besimultaneously filled, it Will be obvious that a single tube or agreater or less number `than that shown may be positioned to be'filledThe driving means to `intermittentlyf.` actuatel the turret tosuccessively-present the tubes to the pockets 22 comprises a'gear 31fixed to the turret shaft 17 meshing with a pinion 32 fixed toone endof'a shaft 33z (Fig ure 12) journalled in a bearing member '34 mountedon a standard 35 fixedto the base 19. The shaft 33 also'jhasfiXedthereto-a mutilated pinion 36 With Which a mutilated gear 37 isadapted to co-operate to drivev the same, said gear being fixed toavshaft 38 (Figure 12) journalled in thestandard. 35 towvhichV a gear 39is fixed' driven` from a pinion 40 fixed to a shaft 41, the latter shaftbeing driven from a suitable'sourceof power by abelt (not shown)passing'around a pulley 42 fixed on a shaft 43 jou'rnalledinv thestandards 18 and25 shown at the right of Figures 1 and 2 by a pinion 44on said shaft meshing with a gear 45 on the shaft 41. The pulley 42 iscoupled and "uncoupled from `the shaft 43 by clutch mechanism (designedin a general Way at 46) thrown into operative and inoperativepositionslby a-lever 47. The

ratio of the gearing'of the-driving means is 5 such vthat after apredetermined'number of successive increments of material have been fedinto the tubes the teeth of the mutilated gear 37 will come in mesh with`the teeth of the mutilated pinion 36 imparting movement thereto andthrough the pinion 32 and gear 31 transmit such movement to the turretadvancing the turret a sufficient distance to deliver vsix 'filled tubesfrom the pockets, and position a succeeding series of six tubes toregister With said pockets.

The emptied tubes are automatically -fed to and the filledtubesdelivered from the turret duringthe movement thereof. For thispurpose a hopper (designated inta general Way by H) for the empty tubesis fixed to the standards 18 at the front of-the'appal ratus, saidhopper having an outlet chute With a support 48` therein 'for the tubesterminating contiguous.` tothe periphery of the turret heads and. theouter Wall of the chute between Which Wall andthe support 4S' the `tubesare guided havingthe extremity shaped to conform to. the curvature'ofthe periphery ofthe turretsheads and lie continuous thereto, assho-Wn at 49, By thisy arrangement of the outlet chute of the hopper H,the tubes as they are discharged are seated in the turret recesses 28.The filled tubes are delivered from the turret to a discharge chute 50fixed to the rear of the standards '18, this chute being arranged withthe outer end to extend between the turret heads and unseat the tubesfrom the turret recesses 28 as the turret is revolved and directing thetubes to a suitable receiver for the same.

To deliver the increments of material successively from the pockets 22into opposite ends of the tubes a series of plungers is provided foreach of said series of pockets operable to deliver the material fromythe opposite pockets simultaneously into op posite ends of the tubes.These plungers comprise rods 51 mounted at one end in carriages 52 tohave reciprocal movement therewith upon rods 23. The opposite ends ofthe rods slidably engage and are guided in CII perforations 52 formed inguide members 53 mounted upon the standards 1S with the perforations inregister with the pockets 22. The carriages are reciprocably mountedupon the rods 28 by rollers 58 to engage at the top and bottom of therods and journalled on studs 59 threaded into the ends of the carriagesand held in position by pilates (Figure 15) secured to opposite ends ofthe carriages.

The pockets 22 are normally open to the hopper outlets to receivematerial therefrom and to shut off said pockets from the hopper outletsduring the feeding of the material from the' pockets to' the tubes bythe plungers and thereby prevent clogging of the material and possiblychoking of the material in the opening of the tubes or throw thematerial from the pockets bac-lr into the hopper, gates or valves 54 areprovided comprising plates slidably mounted to have movement in guideways formed between the top of the guide members 53 for the plungers andthe members 55 (Figure 8) mounted in spaced relation to said guidemembers Thegates 54 are made of relatively thinsheet metal and toprevent distorting of said gates and the consequent wedging thereof inthe guideways reinforcing means are provided for the gates within thehoppers and which also serve as guides forI the gates in the hoppers,

said means consisting of tie rods 92 extending transversely of thehopper in position above the pockets as shoivn in Figures 4 and 5.

Movement is imparted to the carriages 52 and thereby to the plungers tofeed the material from the pockets 22 by levers 56 pivotally supportedat one end upon the base 19 and the opposite ends bifurcated andengaging pins 57 extending transversely of aA 'recessed portion in thebottom ofthe carriages. rllhe carriages with the-plungers are normallymaintained in position' against buffers Gl of resilient material such asrubber,

adjacent the standards 25 by Weights 62 carried by cables or straps 63passing over pulleys 64 and connected to the carriages. Intermittentmovement of successive predetermined extent is imparted to the carriages.and p'lungers to feed the material from the extent will be imparted tothe carriages and` plungers as shown in Figure 5, and this movement willbe successively decreased until the tubes are filled with the material.The plungers are adapted to participate in the reciprocable movement ofthe carriages and.

to have longitudinal yielding movement independent of the carriages, andfor this purpose are slidably mounted in opposite walls of a recess inthe top of the carriages and maintained in position with collars 71 onthe plungers in engagement with the forward wall of said recess bysprings 72 coniinedvby said collars and the rear wall of the recesses,as clearly shown in Figures 4 and 5.

rlhe gates or valves 54 have a pin and slot connection 78 withlevers 74pivotally supported upon the base and connected by links 75 with. levers76 also pivotally supported upon the base and maintained in positionwith the pockets 22 opened to the hopper outlet, as shown in Figure 4,by spring 77 and with rollers 7 8 in engagement with cam wheels 7 9fixed on a shaft 67, said cam wheels having a plurality of cam faces andequal in number to the number of cam faces on the cam wheel65. The camwheels and 79 are conccmitantly rotatable and so arranged and timed thatthe movement of the gates 54 are slightly in advance of the movements ofthe plungers to sluit olf the material receiving pocket 22 from thehopper outlets during the feeding movements of the plungers and opensaid pockets 8l to overhang the `extended ends of the;i
